Bent Sheet Metal Parts

Bent Sheet Metal Parts are one of the most fundamental and widely used components in sheet metal fabrication. Precise control of bending angles and dimensions is essential to ensure proper assembly fit and structural stability.

The standard bending angle tolerance is controlled within ±0.3° for 90° bends. Unfolded (flat pattern) dimension tolerance is maintained within ±0.15 mm, while overall length and width tolerances are controlled within ±0.2 mm. For high-precision applications, tolerances can be further tightened to ±0.08 mm.

The minimum inside bending radius is generally set to be equal to or greater than the material thickness, following standard forming principles to avoid cracking or material stress failure.

In one application case involving Z-shaped structural parts, previous suppliers experienced cracking at bend points. After switching to DC03 deep-drawing steel and optimizing bending sequence and tooling design, the final Bent Sheet Metal Parts were produced without any cracking issues.

Material thickness ranges from 0.6 mm to 5.0 mm, supporting both micro-bending for thin sheets and heavy-duty bending for thicker plates. Common geometries include L-shapes, U-shapes, Z-shapes, and C-shapes, as well as multi-step continuous bending structures.

Each Bent Sheet Metal Parts is formed according to precise geometric requirements to ensure accurate fit and repeatable assembly performance.

After bending, additional processes such as tapping, flanging, embossing, and chamfering can be applied depending on functional requirements. Thread sizes, flange heights, and structural reinforcement features are fully customizable based on customer drawings.

Material options include SPCC, DC03 deep-drawing steel, SUS304 stainless steel, and 5052 aluminum alloy. High-ductility materials are recommended for complex bending structures to reduce the risk of cracking and deformation.

Surface finishing options include deburring, electroplating, powder coating, and localized protective coatings. Multi-section bends, arc bends, and combined structural geometries can also be manufactured according to design specifications.

Sample production time is typically 3–5 days, depending on complexity.
